Aluminium profile drill jig for blind joints

This jig works in combination with four 625 bearings to make precise 5mm holes in your 2020/2040/4040 aluminium profile with 20mm of distance to create a perfect blind joint holes!

It can be used with only two bearings in total, but I strongly advise the use of four!

Better to use PETG or ABS for rigidity.
